These magnets make cleaning the aquarium glass easy.

The cleaning surface of the inner part removes the algae layers. The surface of the outer magnet is covered with a particularly fine synthetic mat that protects the glass. The magnets have an oar that allows attaching a piece of string for retrieving it.

FOR USE WITH GLASS AQUARIUMS ONLY.
